How do I fix the google-standards audit test in WebCare Pro Auditor?

Ensure Largest Contentful Paint (LCP) renders in under 2.5 seconds by preloading hero assets. Keep Interaction to Next Paint (INP) under 200ms by minimizing main-thread blocking JavaScript. Prevent Cumulative Layout Shift (CLS) by explicitly reserving width and height attributes on images and video containers. Enable edge caching and Brotli/Gzip compression via Cloudflare or Nginx.

Technical Architecture & In-Depth Details

Core Web Vitals in 2026

Google's modern performance criteria evaluate real user sessions across three core metrics:

LCP (Largest Contentful Paint): How fast the main visible content loads. Target: ≤ 2.5s.
INP (Interaction to Next Paint): How responsively the page reacts when tapped or clicked. Target: ≤ 200ms.
CLS (Cumulative Layout Shift): Whether page elements jump unexpectedly while rendering. Target: ≤ 0.1.

Passing all three thresholds provides a proven ranking boost in Google organic search and AI overviews.
